The [Stateless OpenPGP Protocol](https://datatracker.ietf.org/doc/draft-dkg-openpgp-stateless-cli/) specification
defines a generic stateless CLI for dealing with OpenPGP messages.
Its goal is to provide a minimal, yet powerful API for the most common OpenPGP related operations.

## Modules

The repository contains the following modules:

* [sop-java](/sop-java) defines a set of Java interfaces describing the Stateless OpenPGP Protocol.
* [sop-java-picocli](/sop-java-picocli) contains a wrapper application that transforms the `sop-java` API into a command line application
compatible with the SOP-CLI specification.
